Oil-increasing cultivation of soybean

1. Variety selection and seed treatment (1) select varieties with high oil content, strong resistance to diseases and insect pests, moderate maturity and full maturity before frost, mainly Kenjiandou 25 and Kenjiandou 27; (2) seed selection before seed description, mix seeds with 0.1-0.3% of the amount of borax seeds. 2. Corn stubble is the best stubble, followed by wheat, sugar beet stubble is the most disadvantageous to the formation of oil content, and continuous cropping soybean is not conducive to the formation of oil content, so heavy stubble land should be avoided. 3. Early sowing at the right time is beneficial to the improvement of oil content, and the local requirement is to finish sowing before May 10. 4. Fertilizing and applying potassium sulfate or potassium sulfate compound can not only supplement potassium but also increase sulfur, which can increase the oil content of soybean. 5. during the full bloom of foliar topdressing, spraying sulfur (40 mg / kg) and boron (200 mg / kg) can increase the oil content by 1% to 2%. Be careful not to apply molybdenum, manganese, platinum and manganese will reduce the oil content. 6. Pest control at the end of July and the beginning of August, foliar spraying 2.5% bromocyanide 30ml / mu to control heart borer and 50% carbendazim 100g / mu to control gray spot can increase oil content, both of which should be used as routine measures for the production of high-oil soybean. 7. Dense planting is not conducive to the increase of oil content, so the density should be reduced properly. 28 ~ 300000 seedlings per hectare of Kenjiandou 25 and 27 are required in this area. 8. If there are conditions for irrigation, soybean can be irrigated from podding stage to grain filling stage to improve oil content. 9. Harvest (1) when the soybean is in yellow maturity, more than 70% of the leaves fall off, and sectional harvest is beneficial to increase the oil content; (2) during harvest, we should adopt single harvest, single storage and single sale of different varieties to prevent mixed beans from reducing oil content.
